Abstract
Description
Technical Field
[0001] The utility model relates to the field of steel wire rope detection equipment, in particular to a steel wire rope electromagnetic detector calibration device based on a comparison sample. Background Art
[0002] During the production of wire ropes, wire ropes based on comparison samples should be tested first. The test results can be used to determine and resolve pre-existing damage that prevents the use of artificial damage. The wire rope based on the comparison sample should match the electromagnetic detection instrument and sensor head used and the specifications of the wire rope being tested. The wire rope used for the comparison sample should be of sufficient length to implement a comprehensive testing operation. Artificial damage on the wire rope comparison sample should include methods of removing or adding breaks formed on the outer wire. Typical break lengths should be 1.5mm, 3mm, 6mm, 12mm, 25mm, 50mm, 100mm, 200mm, 400mm and 800mm. The typical distance between the breaks is 760mm. The break should be at least 1200mm away from the end of the wire rope. The length of some breaks may not be required.
[0003] In the process of using electromagnetic detector to test sample wire rope, in order to ensure the accuracy of the test results, the electromagnetic detection instrument often needs to reciprocate along the surface of the wire rope to perform multiple and comprehensive testing operations. If the wire on the surface of the wire rope is broken, the broken wire and the wire at that position lose their restraints and are likely to protrude from the surface of the wire rope, resulting in a raised obstacle. When the electromagnetic detector is in reciprocating motion, the raised broken wire is likely to hinder it, which is further likely to cause the electromagnetic detector to become stuck, affecting the efficiency of the test work. Utility Model Content
[0004] In order to solve the above problems, the present application provides a wire rope electromagnetic detector calibration device based on comparison samples.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a calibration device for a wire rope electromagnetic detector based on a comparison sample, comprising an openable and closable detection body and a supporting body. When the detection body and the supporting body are in a closed connection state, a channel is formed for the wire rope to pass through. Both ends of the channel are provided with a group of guide arc plates symmetrically distributed upper and lower. When the upper and lower guide arc plates are in a closed state, they can cover the wire rope.
[0006] The guide arc plates are all provided with jumpable rollers. During the synchronous movement of the detection body and the support body, the rollers roll in contact with the steel wire rope inside the guide arc plates, and the rollers can jump to avoid the obstruction of the protrusions on the surface of the steel wire rope.
[0007] Furthermore, both ends of the roller are connected with connecting arms via a rotating shaft, and the ends of the connecting arms on both sides of the same roller away from the rotating shaft are connected via a limiting shaft, and both ends of the limiting shaft are connected with positioning arms via bearings, and the positioning arms are arranged on the guide arc plate. When the roller encounters a raised obstacle during sliding, the roller and the connecting arm swing around the limiting shaft.
[0008] Furthermore, the connecting arm is provided with a guide piece that can rotate synchronously with the connecting arm, and the positioning arm is provided with a semicircular accommodating support. The two ends of the accommodating support are respectively connected to the two sides of the guide piece through pressure springs. In a natural state, the guide piece is located directly below the accommodating support. When the guide piece rotates toward the two ends of the accommodating support, the pressure springs located in that direction contract.
[0009] Furthermore, a rotatable locking rod is provided on the inner side of the accommodating tray, and through holes are provided at both ends of the accommodating tray to accommodate the locking rod to be screwed in and out, and the through holes are opposite to the position of the pressure spring. When the locking rod passes through the through holes and is screwed out to the outside of the accommodating tray, the locking rod is inserted into the inner side of the pressure spring to intercept the guide plate from sliding toward the end of the accommodating tray.
[0010] Furthermore, an extension rod is provided at the center of the locking rod, and an arc channel that can accommodate the reciprocating movement of the extension rod is provided on the surface of the positioning arm. A jacket is provided at one end of the extension rod that passes through the arc channel and is exposed to the outside of the positioning arm.
[0011] Furthermore, the support body is provided with an electric push rod whose height can be adjusted, and the electric push rod is provided with a driving seat which can move synchronously with the electric push rod.
[0012] In summary, the technical effects and advantages of the utility model are:
[0013] When the detection body and the support body in the utility model move in different directions, the roller and the connecting arm that first contact the raised obstacle can jump in the direction opposite to the raised obstacle, and respond quickly to jump over the raised obstacle. This enables the part of the raised obstacle to be quickly identified by the detection body. In actual use, the avoidance direction of the roller and the connecting arm can change with the change of the moving direction of the detection body and the support body. When the moving directions are different, it can also ensure that the roller and the connecting arm can quickly respond to avoidance without adjusting the direction of the roller and the connecting arm.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Embodiment 1:
[0022] refer to Figure 1 , Figure 2 The wire rope electromagnetic detector calibration device based on the comparison sample shown in the figure includes an openable detection body 1 and a support body 2. When the detection body 1 and the support body 2 are in a closed connection state, a channel for the wire rope to pass through is formed. A set of upper and lower symmetrically distributed guide arc plates 5 are provided at both ends of the channel. When the upper and lower guide arc plates 5 are in a closed state, the wire rope can be covered. As the detection body 1 and the support body 2 continue to move, the guide arc plates 5 move outside the wire rope.
[0023] The guide arc plates 5 are each provided with a jumpable roller 6. During the synchronous movement of the detection body 1 and the support body 2, the roller 6 rolls in contact with the steel wire rope inside the guide arc plate 5, and the roller 6 can jump to avoid the raised obstacles on the surface of the steel wire rope.
[0024] Both ends of the roller 6 are connected to the connecting arms 7 through the rotating shaft. The connecting arms 7 at both ends of the channel face in opposite directions. When the detection body 1 and the support body 2 move in different directions, the roller 6 and the connecting arm 7 that first contact the raised obstacle can jump in the direction opposite to the raised obstacle, respond quickly, and jump over the raised obstacle. The part of the wire rope with the raised obstacle can quickly enter the inner side of the detection body 1 and the support body 2 and be recognized by the detection body 1.
[0025] The connecting arms 7 located on both sides of the same roller 6 are connected at one end away from the rotating shaft through a limit shaft 8. Both ends of the limit shaft 8 are connected to positioning arms 9 through bearings. The positioning arms 9 are arranged on the guide arc plate 5. When the roller 6 encounters a raised obstacle during sliding, the roller 6 and the connecting arm 7 actually swing around the limit shaft 8.
[0026] like Figure 3 , Figure 4 As shown, the connecting arm 7 is provided with a guide piece 71 which can rotate synchronously therewith, and the positioning arm 9 is provided with a semicircular accommodating support 10, and the two ends of the accommodating support 10 are respectively connected to the two sides of the guide piece 71 through pressure springs 11. In a natural state, the guide piece 71 is located directly below the accommodating support 10. When the guide piece 71 rotates toward the two ends of the accommodating support 10, the pressure springs 11 located in this direction are contracted, and the roller 6 and the connecting arm 7 can smoothly avoid the raised obstacles, leaving space for the raised obstacles to pass through, and the detection body 1 and the support body 2 can slide smoothly to implement the detection operation.
[0027] The elastic potential energy of the pressure spring 11 can enable the roller 6 and the connecting arm 7 to quickly return to their original positions after avoiding the raised obstacle, clamping on the surface of the wire rope, and rollingly contacting the wire rope as the detection body 1 and the support body 2 slide.
[0028] Since the two ends of the accommodating support 10 are respectively connected to the two sides of the guide plate 71 through the pressure spring 11, the avoidance direction of the roller 6 and the connecting arm 7 can be changed as the moving direction of the detection body 1 and the supporting body 2 changes. It is suitable for different moving directions of the detection body 1 and the supporting body 2 without adjusting the orientation of the roller 6 and the connecting arm 7.
[0029] Embodiment 2:
[0030] like Figure 3 , Figure 4As shown, during the sliding of the detection body 1 and the support body 2, according to the sliding direction, if there is a raised obstacle on the path, when the roller 6 and the connecting arm 7 swing around the limit axis 8, the swing direction must be opposite to the direction of the raised obstacle in order to smoothly make a swing response and avoid the raised obstacle.
[0031] Since the connecting arms 7 at both ends of the channel face in opposite directions, and the roller 6 and connecting arm 7 that first contact the raised obstacle can make a swing response in time, in order to limit the roller 6 and connecting arm 7 that finally contact the raised obstacle to only rotate in the direction opposite to the direction of the raised obstacle, a swing response is generated in time, thereby reducing the stuck phenomenon of the roller 6 that finally contacts the raised obstacle. A rotatable locking rod 12 is provided on the inner side of the accommodating tray 10, and both ends of the accommodating tray 10 are provided with a through hole 101 that can accommodate the locking rod 12 to be screwed in and out, and the through hole 101 is opposite to the position of the pressure spring 11. When the locking rod 12 passes through the through hole 101 and is screwed out to the outside of the accommodating tray 10, the locking rod 12 is inserted into the inner side of the pressure spring 11, and the intercepting guide piece 71 slides toward the end of the accommodating tray 10.
[0032] Therefore, after this operation is performed, the guide piece 71 can be limited to rotate in a specified direction, so that the roller 6 and the connecting arm 7 that are finally in contact with the raised obstacle can only rotate in the direction opposite to the direction of the raised obstacle, effectively avoiding the phenomenon of the detection body 1 and the support body 2 being stuck due to the untimely jumping of the rollers 6 at both ends of the channel.
[0033] like Figure 4 As shown, an extension rod 13 is provided at the center of the locking rod 12, an arc-shaped channel is provided on the surface of the positioning arm 9 to accommodate the reciprocating movement of the extension rod 13, and a jacket 14 is provided at one end of the extension rod 13 that passes through the arc-shaped channel and is exposed to the outside of the positioning arm 9. When the locking rod 12 is inserted into the inner side of the pressure spring 11 and the sliding path of the guide piece 71 is intercepted, the jacket 14 can be controlled to rotate on the extension rod 13 until the jacket 14 is pressed against the surface of the positioning arm 9, which has a positioning effect on the extension rod 13 and the locking rod 12, and effectively prevents the extension rod 13 from deviating.
[0034] like Figure 2 As shown, in order to facilitate the support body 2, an electric push rod 3 whose height can be adjusted is provided, and a driving seat 4 which can move synchronously with the electric push rod 3 is provided on the electric push rod 3. The driving seat 4 is controlled by a circuit, and the staff can remotely control it to achieve the purpose of driving the electric push rod 3, supporting the body 2, and detecting the sliding of the detection body 1 outside the wire rope.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
